2) No One is a side project of Leif & Lars Hansen (Oneiroid Psychosis).

Leif basically locked himself in an attic room with little more than a sampler, a TV set, and a four track recorder. The resulting disjointed noise collage sat on a shelf for several months until Lars decided to transfer the sounds onto a digital eight track, while adding new samples and sound processing effects. These experiments were released in a very limited quantity on Feedback and are no longer available.

Free tracks can be downloaded at their offical website, http://oneiroidpsychosis.com/htm/noone.htm.

3) NoOne (stylized as NoOne (without the space)) is an unsigned acoustic act of Scott Carlson.
